SKU = inventory unit. That is, the basic unit of inventory in and out measurement can be pieces, boxes, pallets, etc.

SKU is used for pricing and managing inventory. For example, a product has many colors and configurations, and each combination of colors and configurations will form a new product. At this time, many SKUs were generated. SKU is also a very common concept in traditional offline industries, especially in the clothing industry. Different colors of the same paragraph are independent SKUs, which need independent bar codes and independent inventory management.

For e-commerce, SKU has another saying:

1, SKU refers to a product, and each product has a SKU, which is convenient for e-commerce brands to identify products.

2. If a product is multicolored, there are multiple SKUs. For example, if a dress is red, white and blue, the SKU code is different. If they are the same, there will be confusion and the wrong goods will be sent.
